Headgasket? 93 Camry Xle V6

My car overheated and now it cranks but won't fire. Checked oil and didn't notice any water. Haven't checked the compression in the cylinders yet. I'm wondering if the computer "tripped" something when it got hot. And where to start checking. Thanks

The water pump had a leak. I noticed that
it was getting hot, gauge was about 3/4 to
the top. I pulled over and with the car
running I topped off the radiator.
Temperature dropped, about 30 minutes
later I tried to start the car but had no luck.

OK...so we have a vehicle that cranks over well...but...will not fire up. I really cannot see a direct connection between a overheat condition and a no start. There is a way to pull computer codes with and without a Scan Tool. As noted above....checking for spark and compression sounds like a good way to go. Checking fuel delivery/pressure/fuel filter should also be included. Checking injector PULSES will require a "Noid" test light which can be purchased at any Auto Parts Store.
